"where we will be in another 50 years is anyone’s guess."
For many of us on here it is more a fact of life rather than a guess in 50 yrs

Just switch to praising budha and you'll get to come back, hopefully to drive th eVette again. LOL
Religion can do anything you want.
50 years ago, they said we'd all have flying cars, and robots would do all our work so we wouldn't have to. Still waiting... Don't know enough about this Astron engine, but looks like it has very small compression / expansion volume to make 400 hp - and there's limits to thermal efficiency of an ICE engine - 60% is unlikely, high efficiency requires high temperatures = NOx. No cooling system? Aluminum internal parts? Without seals and lubrication, leakage and wear would be problematic. Can it make full power and last longer than a few hours in the lab? Stay tuned....
Hydrogen is a seriously problematic fuel - expensive, usually takes more energy to make it than it contains. It also has a very low energy content, has to be compressed to a zillion psi to store it the fuel tank, requires exotic materials, and the tiny molecules leak through seals. And it has a tendency to explode. The only thing worse is highly toxic anhydrous ammonia, which is also being peddled as an alternative to fossil fuels. Skip the hydrogen, and use the electricity to charge batteries.
If only the US government would release some of that alien technology from Area 51...

Formula 1 engines currently have over 50% efficiency and will probably improve on that with the upcoming 2026 regulations. As for hydrogen, it makes a wicked good bomb , lol . I doubt it will ever see widespread use in automobiles for a number of other reasons but that’s not enough to discourage our government from sinking millions into trying to do so . There are over 145,000 gas stations in the US alone . Think of the cost of converting them to hydrogen, or electric vehicle charging stations for that matter. They are wanting us all to be in the bike lane I’m afraid.
Hydrogen is flammable and can be explosive, with the following characteristics:
- Flammability range
Hydrogen is flammable in air concentrations between 4% and 75%. This is a much wider range than other common fuels, such as natural gas, which has a flammability range of 7% to 20%.
- Ignition energy
Hydrogen requires very little energy to ignite, especially under optimal combustion conditions. A small spark can ignite hydrogen.
- Flame
Hydrogen burns with a pale blue flame that's almost invisible during the day. Hydrogen fires also produce low radiant heat, so it can be difficult to sense the presence of a flame until you're very close to it.
- Explosiveness
Hydrogen can be explosive at concentrations between 18.3% and 59%. However, hydrogen is unlikely to explode in open air because it rises quickly.
- Safety
To prevent a fire or explosion, you should prevent hydrogen from mixing with an oxidizer. You can do this by ensuring proper system design, installation, and maintenance. If a leak occurs, you can dilute the hydrogen with ventilation to keep the concentration below its lower flammable limit.

Car guys love to think they’ll still be hooning long after social security kicks in, but the truth is, life often gets in the way. That’s nothing to be ashamed of, though it does give us extra reason to celebrate when we see somebody like Annie Koehler.

As well as, lol .
The main challenges in using hydrogen as a fuel include:
• Production Costs: Most hydrogen is currently produced from fossil fuels, which is energy-intensive and environmentally damaging. Green hydrogen, while cleaner, is significantly more expensive, costing $5-7 per kg compared to $1-2 for grey hydrogen.
• Infrastructure: There is a lack of adequate infrastructure for hydrogen production, storage, and distribution, including refueling stations. Building this network requires substantial investment and coordination.
• Storage and Distribution: Hydrogen’s low volumetric energy density makes it difficult to store and transport safely. High-pressure tanks or specialized pipelines are necessary, complicating logistics.
• Safety Concerns: Hydrogen is highly flammable, necessitating strict safety protocols to gain public trust and acceptance.
Addressing these challenges is crucial for the widespread adoption of hydrogen as a viable fuel source.
Of course none of the above will prevent the sinking of mucho tax dollars into chasing it .
If you thought getting rear ended in a Pinto was scary….
So is gasoline, propane,. ethanol, natural gas .... ! What is your point! lol

Maybe we should stick with diesel , it doesn’t explode really well until you mix it with nitrogen fertilizer…
point is that you won’t see me , or anyone other than test drivers , in a vehicle powered by it anytime soon.
